Subject: [oc] patents and logic cores
Hi Guenter,
I don't know the answer to the legal technicalities you are asking, but I
would recommend you stay away from pattent protected stuff. Any
lawsuit will bring you lots of headaches and financial harm even if your
action is not necesarily illegal.
Thanks
